The war ending just in time, some formidable projects didn't make it into action. While Messerschmidt's jets (notably the ME-262) were in production and causing concern for the Allies, Focke-Wulf, builders of the FW-190, had their own jet ideas being planned out. Before they could be built, the war had ended but the designs look rather modern for the mid 40's.
Developed at the same time (hence some similarities), first there was the Focke-Wulf TA-283:
Along with the nicely raked wings, the rear mounted engines are actually ramjets. To take off and get to speed to light them off, a Walter KWK 509 rocket engine (the same one as used in the ME163 Komet) was used. Top speed estimated at 693 mph.
Using some same principles such as rear mounted ramjets, Focke-Wulf's Super Lorin had both a rocket engine and small turbojet to take-off before ramjet power could be developed. Topping out at over 620 mph. it was intended as in interceptor against incoming bombing fleets.
On one hand, had the war lasted longer and these reached production they would have been quite an asset for German air defense, but on the other hand the end of the war in Europe came about just weeks before the first Trinity atomic bomb tests.
